Anybody know the size for the freeze plug that needs to be put in the timing cover when the waterpump drive shaft has been removed?

My CSI didn't come with the one for the WP housing either but I've been told that a 1-1/8" freeze plug will do the job.

Any help would be appreciated.

 

1 1/4". 1 1/8" is for the w/p housing.

 

Thanks man...much appreciated.
